Municipal road concrete pavement construction method

WEI JIANMING

The invention discloses a municipal road concrete pavement construction method. The municipal road concrete pavement construction method comprises the following steps:1, base layer raw materials are prepared; 2, cement stabilized macadam obtained in the step 1 is flatly laid, paved, rolled and cured; 3, paving and vibrating are performed; 4, joint construction is performed, namely pull rods are installed after formwork erecting and before concrete pouring, the pull rods of longitudinal construction joints penetrate through pull rod holes of formworks, and longitudinal joint grooves are suitable for being sawn through a joint sawing machine after concrete hardening; 5, trowelling and skid resistance are conducted;and6, maintenance and joint filling are conducted; According to the concrete pavement construction method, the long-term repeated deformation resistance of concrete is improved, and the possibility of concrete tension fracture is greatly reduced, so that the use performance ofthe concrete pavement is improved.

本发明公开了一种市政道路混凝土路面施工方法，包括如下步骤：步骤1基层原料的配制，步骤2将步骤1得到的水泥稳定碎石平铺、摊铺、碾压完成及养生；步骤3摊铺和振捣，步骤4接缝施工；拉杆在立模后浇筑混凝土之前安设，纵向施工缝的拉杆则穿过模板的拉杆孔安设，纵缝槽宜在混凝土硬化后用锯缝机锯切；步骤5、抹平与防滑，步骤6、养护和填缝；本发明混凝土路面施工方法，提高混凝土抵抗长期反复变形的能力，大大减少了混凝土拉裂的可能性，因而提高了混凝土路面的使用性能。
